Memory Gauge 177ºC

Memory Pressure-Temperature Sensor


The EZGAUGE Series provides a wellbore for the Temperature and Pressure measurement with a quality and reliability in very long duration operations. The high accuracy and high resolution sensors can be operated by non-specialists and provide substantial cost savings. They need minimum logistics for their operation and maintenance.
High reliability power batteries has been tested up to 6 months of continuous downhole recording, the data is downloaded using a very user friendly software that runs on any PC with Windows XP/Win7/W10 operating system.
